uni pump motor should fit, maybe usual socket to wire tags needed.
As for reset, cannot picture this one in my head, but the usual way is to hold a start button (or prog select if it only has the one) down, or turn off at the mains and select a different program. Failing that, press start or prog select button 4 times at switch on before the lights come on and then swtich off again.
No prog select button on this, five large, square programme buttons on left then a mains On/Off button next to the start button on the right, holding it down doesn’t seem to have any effect after the prog has started.
